MACHINE FOR APPLYING FERRULES OR BANDS TO HOSE.

To all whom t may concern: Y

Be it known-that LHnNnY Gines, acitizen of the United States, and a resident of Chicago, county of` Cook, and State of Illinois, have invented certain new and useful Improvements 'in Machines for Applying Ferrules or Bands to Hose, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing, formingpart of this specification.

The `present inventionhas for its object to provide a simple, cheap, durable and effective construction of device whereby ferrules, such asare used at the ends of a hose may be quickly, evenly and securely con-` tracted upon the hose.

The `invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the claims at the end of this specification.

Figure l is a view in side elevation of a machine `embodying my invention. Fig. 2 isa view in central vertical section on line 9.-2 of Fig. 3, the jaws beingshown in elevation. Fig. 3 is a view in vertical section on line 3 3 of Fig. 2. Fig. 4l is a view in cross-section on line 4.-4 of Fig. 2.

A designates a stationary standard adapted to be bolted to a work bench or in any other convenient"location, the base a of the standard being provided with suitable holt holes for such purpose. The `standard A is shown as formed with the central portion a in which are formed the radial chambers or recesses c2 adapted to receive the jaws B which `are held in manner free to slide radially within said recesses, the central portion of the standard being open, as shown. The standard A is also preferably provided with a chamber at one side, adapted to receive a plate C having a central opening c, this plate bearing against the sides of the jaws B, the plate C being held in place by suitable screws c that enter threaded holes in the portion a of the standard A. Each of the jaws B is provided with a stud or pin b projecting outwardly therefrom and passing through a cam'shaped slot l that is formed in a movable plate D that is revolubly mounted upon the standard A. This plate D is formed with a central opening d through which the hose may be passed Specification of Letters Patent.

when a ferrule is to be applied thereto. As shown, the periphery of the standard A is reduced to perlnit the flanged edge (Z2 of the plate D to set over the same and, when the plate D is in position for ilse, as shown in the several views of the drawing, the flange /Z2 of the plate D will abut against the peripheral [lange as of the standard A. The periphery of the standard A is also formed with a semi-cylindrical channel a, and similarly the interior of the flange (Z2 of the plate D` is formed with an annular semi-cylindrical channel (Z3, these semi-cylindrical channels a* and (Z3 serving to receife the anti-friction balls E. Preferably, the flange di of the plate D is provided with a hole d through which the balls E may be inserted into the annular channels formed respectively in the periphery of the standard A of the flange (I2 of the plate D, and this hole Il* will be closed by a suitable screw plug di".

To the plate D is attached a suitable liandle l" and for convenience in attaching this handle, the plate D has cast integral therewith a socket el having a threaded opening into which the correspondingly threaded end of the handle will be screwed.

lVhen the parts are assembled for use, as shown in the several views of the drawing, and with the handle in the position seen in Fig. l, the pins Z) that project from the jaws i will rest in the outer ends of the inclined or cam-shaped grooves (Z of the plate D and at such time thejaws B will be at the outermost points of their travel in the radial recesses az, the curved inner ends b5 of the jaws being then in their extreme open position. If new aferrule is to be applied to the end of a hose, the end of the hose with the ferrule encircling` the same will be placed within the machine with the ferrule opposite the curved ends b5 of the jaws B and the operator will turn the handle F in the direction of the arrow, Fig. l. This movement of the handle F will cause a correspending partial revolution of the plate D, and as the plate D is thus revolved, the inclined outer walls of the grooves (l will force the pins Z) and the jaws B inward radially, causing the curved inner ends b5 of the jaws to tightly contract the ferrule upon the hose. After the ferrule has been thus contracted upon the hose, the operator will turn the handle F in reverse direction, thereby causing the plateD to be correspondingly reversed so that the inner walls of the inclined grooves i of the plate will cause the pins b and the jaws B to move radially outward and so release the inner ends b5 of the jaws from the ferrule.

Ifit is desired to change the jaws B, it is only necessary to remove the guard plate C when jaws of any required size may be substituted. Y

By providing a revoluble plate having in.- clined or cam-shaped surfaces for controlling, the radial movement of the clamping jaws, an exceedingly simple and effective means is afforded for contracting the ferrules, and by providing ball bearings between the revoluble plate and the standard, the operation of the plate is effected with the least possible exertion. Obviously, so long as the anti-friction balls E are in position for use, the plate D is securely held upon the standard A.

It is manifest that the precise details of construction above set out may be varied without departure from the spirit of the invention. y

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

l. A machine for applying ferrules or bands to hose comprising a standard having a circular periphery and an offset part adapted for attachment to a fixed support, said standard having a central opening and a series of radial recesses extending` from said opening, jaws movably mounted in said recesses and arranged to abut in their innermost position, an oscillating clamping plate abutting against one face of said standard and having a flange overlapping and interlocked with the circular periphery thereof and arranged to hold said jaws in position, said clamping plate having a central opening and a series of cam slots about said opening, laterally projecting pins fixed to said jaws and engaging said cam slots and a handle connected to said clamping plate for periphery of said standard, jaws held in the v recesses of said standard by said bearing and clamping plates, said oscillating clamping plate having a central opening and a series of cam slots about said opening, pins fixed to said jaws and vprojecting laterally into said cam slots and a handle connected to said clamping plate for oscillating the same,

substantially as described.

3.,A machine for applying ferrules ork bands to hose comprising a fixed standard having a circular periphery, a central opening and a series of radial recesses extending from said opening, an oscillating clamping plate abutting against one face of said standard, closing the open sides of said recesses and having a laterally projecting flange overlapping the circular periphery `of said standard, a row of anti-friction'balls interlocking said parts, a series of radially movable jaws held in position in the re-` cesses of said standard by said clamping plate, said jaws being arranged to abut into closed position, said clamping plate having a central opening and a series of cam slots about said opening, and pinsl fixed to said jaws and projecting laterally into said cam slots, substantially as described.
